Vehicle Location Sharing Server Maintains Settings After Ignition Off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle location sharing systems lose continuity when the vehicle is restarted, requiring users to reinitialize settings, which deteriorates convenience and disrupts the sharing of information.
Innovation Solution
A location sharing system that maintains setting information between a vehicle device and a target service node even after ignition is turned off, and extends sharing time when the initial period elapses, using a location sharing server to manage and restart the service based on vehicle state information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the vehicle ignition is turned off, then the vehicle stops consuming energy, but the location sharing settings are initialized and service continuity is lost
Solution Approach 1:
The system performs preliminary actions by saving location sharing setting information to the server before the vehicle ignition is turned off. When the vehicle restarts, the server automatically restores these settings without requiring user reconfiguration, thus maintaining service continuity while allowing the vehicle to stop consuming energy during shutdown.
Solution Approach 2:
The server acts as an intermediary between the vehicle device and the user. It stores location sharing setting information and automatically restores it when the vehicle restarts, mediating the gap between vehicle shutdown (energy saving) and service continuity (setting persistence).
2Reliability
If the location sharing service is restarted after ignition off, then service continuity is maintained, but additional time is required for settings restoration
Solution Approach 1:
The system performs preliminary actions by pre-saving location sharing settings to the server before vehicle shutdown. This eliminates the need for time-consuming setting restoration after restart, as the server automatically retrieves and applies the saved settings immediately upon vehicle startup.
Solution Approach 2:
The system implements self-service by enabling the server to automatically restore location sharing settings without requiring user intervention. The server independently handles the settings restoration process, eliminating manual configuration time and maintaining service continuity seamlessly.
3Duration of action of moving object
If the sharing time is extended beyond the initial period, then continuous location sharing is maintained, but system complexity increases
Solution Approach 1:
The system ensures continuity of useful action by automatically extending the sharing time period. When the initial sharing time expires, the server seamlessly续期 the service without interrupting location sharing, maintaining continuous operation while simplifying time management through automated extension logic.
4Productivity
If the vehicle location is continuously monitored, then real-time location sharing is provided, but energy consumption increases
Solution Approach 1:
The system implements periodic action by monitoring and transmitting vehicle location information at predetermined time intervals rather than continuously. This approach maintains real-time location sharing service efficiency while significantly reducing vehicle energy consumption during location monitoring and transmission.

AI summary
A location sharing system of a vehicle includes: a vehicle device configured to monitor and provide location information and state information of the vehicle; a plurality of service nodes configured to provide a location-based service based on the location information of the vehicle; and a location sharing server configured to set a first sharing period of time and a target service node for providing a location sharing service between the vehicle device and the plurality of service nodes and to transmit the location information of the vehicle to the target service node during the first sharing period of time. The location sharing server determines a remaining period of time in the first sharing period of time to restart the location sharing service between the vehicle device and the target service node depending on a determination result.
